The Korean star caused a sensation in Asia, but he was not as strongly sought after in Japan as in China, Malaysia and Thailand. Reason 1: Japan has formed its own style and high quality a long time ago, no matter movies, songs or street dances, so it is not easy for foreign monks to recite scriptures there. 2.BOA has only opened the Japanese market in Korea for a few years. Before, only one Korean singer ranked first in the Japanese public trust list for more than 20 years, and now TVXQ!! It took more than 20 years to appear on it. It can be seen that Korean singers have a hard time in Japan. 3. Japan has a high demand for singers, who basically sing live, while South Korea pays attention to dance, and the national slogan is entertainment for all, so singing in Japan gained great points, but those fancy moves didn't get many points. TVXQ! is an example. When it was popular in Korea and even in Asia, only a few hundred people could hold concerts in Japan, so it was much more popular to take on increased singing skills.
